Ashley X
The Ashley Treatment refers to a controversial set of medical procedures performed on an American child, "Ashley X". Ashley, born in 1997, who has severe developmental disabilities due to static encephalopathy; she is assumed to be at an infant level mentally, but continues to grow physically. The treatment included growth attenuation via high-dose estrogens, hysterectomy, bilateral breast bud removal, and appendectomy. In June 2016, after 18 years of searching, Ashley's condition was determined to be the result of a ''de novo'' (not inherited, i.e. a mutation) and non-mosaic single-nucleotide polymorphism in the GRIN1 gene, which is implicated in neurotransmission. The principal purpose of the treatment was to improve Ashley's quality of life by limiting her growth in size, eliminating menstrual cramps and bleeding, and preventing discomfort from large breasts. The combination of the surgery and the estrogen therapy attracted much public comment and ethical analysis in early 20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Developmental Disabilities
Developmental disability is a diverse group of chronic conditions, comprising mental or physical impairments that arise before adulthood. Developmental disabilities cause individuals living with them many difficulties in certain areas of life, especially in "language, mobility, learning, self-help, and independent living".Center for Disease Control and Prevention. (2013)Developmental disabilities.Retrieved October 18, 2013 Developmental disabilities can be detected early on and persist throughout an individual's lifespan. Developmental disability that affects all areas of a child's development is sometimes referred to as global developmental delay. The most common developmental disabilities are: * Motor disorders, and learning difficulties such as dyslexia, Tourette's syndrome, dyspraxia, dysgraphia, Irlen syndrome, and dyscalculia. * Autism and Asperger syndrome are a series of conditions called autistic spectrum disorders that causes difficulties in communications.

Pediatric Endocrinologist
Pediatric endocrinology (British: Paediatric) is a medical subspecialty dealing with disorders of the endocrine glands, such as variations of physical growth and sexual development in childhood, diabetes and many more. By age, pediatric endocrinologists, depending upon the age range of the patients they treat, care for patients from infancy to late adolescence and young adulthood. The most common disease of the specialty is type 1 diabetes, which usually accounts for at least 50% of a typical clinical practice. The next most common problem is growth disorders, especially those amenable to growth hormone treatment. Pediatric endocrinologists are usually the primary physicians involved in the medical care of infants and children with intersex disorders. The specialty also deals with hypoglycemia and other forms of hyperglycemia in childhood, variations of puberty, as well other adrenal, thyroid, and pituitary problems. Many pediatric endocrinologists have interests and expertise in b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breast Cancer
Breast cancer is cancer that develops from breast tissue. Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, milk rejection, fluid coming from the nipple, a newly inverted nipple, or a red or scaly patch of skin. In those with distant spread of the disease, there may be bone pain, swollen lymph nodes, shortness of breath, or yellow skin. Risk factors for developing breast cancer include obesity, a lack of physical exercise, alcoholism, hormone replacement therapy during menopause, ionizing radiation, an early age at first menstruation, having children late in life or not at all, older age, having a prior history of breast cancer, and a family history of breast cancer. About 5–10% of cases are the result of a genetic predisposition inherited from a person's parents, including BRCA1 and BRCA2 among others. Breast cancer most commonly develops in cells from the lining of milk ducts and the lobules that supply these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archives Of Pediatrics & Adolescent Medicine
''JAMA Pediatrics'' is a monthly peer-reviewed medical journal published by the American Medical Association. It covers all aspects of pediatrics. The journal was established in 1911 as the ''American Journal of Diseases of Children'' and renamed in 1994 to ''Archives of Pediatrics & Adolescent Medicine'', before obtaining its current title in 2013. The journal's founding editor-in-chief in 1911 was Abraham Jacobi. The articles in that first volume of the journal were mostly observational studies focused on the major causes of illness and death in children at the start of the 20th century.

Growth Plates
The epiphyseal plate (or epiphysial plate, physis, or growth plate) is a hyaline cartilage plate in the metaphysis at each end of a long bone. It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length). The plate is only found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line. This replacement is known as epiphyseal closure or growth plate fusion. Complete fusion can occur as early as 12 for girls (with the most common being 14-15 years for girls) and as early as 14 for boys (with the most common being 15–17 years for boys). Structure Development Endochondral ossification is responsible for the initial bone development from cartilage in utero and infants and the longitudinal growth of long bones in the epiphyseal plate. The plate's ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hormone Therapy
Hormone therapy or hormonal therapy is the use of hormones in medical treatment. Treatment with hormone antagonists may also be referred to as hormonal therapy or antihormone therapy. The most general classes of hormone therapy are oncologic hormone therapy, hormone replacement therapy (for menopause), androgen replacement therapy (ART), oral contraceptive pills, and transgender hormone therapy. Types * Hormone replacement therapy (HRT), also known as menopausal hormone therapy (MHT), is for women with menopausal symptoms. It is based on the idea that the treatment may prevent discomfort caused by diminished circulating estrogen and progesterone hormones, or in the case of the surgically or prematurely menopausal, that it may prolong life and may reduce incidence of dementia. It involves the use of one or more of a group of medications designed to artificially boost hormone levels. The main types of hormones involved are estrogen, progesterone, or progestins, and sometimes, test ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Children's Hospital And Regional Medical Center (Seattle)
Seattle Children's, formerly Children's Hospital and Regional Medical Center, formerly Children's Orthopedic Hospital, is a children's hospital in the Laurelhurst neighborhood of Seattle, Washington. The hospital specializes in the care of infants, children, teens, and young adults aged 0–21 in several specialties. History The hospital was founded as the seven-bed Children's Orthopedic Hospital in 1907 by Anna Herr Clise after her 5-year-old son, Willis, died of inflammatory rheumatism in 1898. It was originally a ward of the downtown Seattle General Hospital. It moved to a cottage on Queen Anne Hill the next year, and in 1911 influential community members including Herbert Gowen and Mark A. Matthews dedicated a full 40-bed hospital at the same location. The library at the hospital was founded in 1946. In 1953, Children's moved to a new campus in Laurelhurst, east of the University of Washington. A research division, Seattle Children's Research Institute (SCRI), was e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thelarche
Thelarche, also known as breast budding, is the onset of secondary breast development, often representing the beginning of pubertal development. It is the stage at which male and female breasts differentiate due to variance in hormone levels; however, some males have a condition in which they develop breasts, termed gynecomastia. Thelarche typically occurs between the ages of 8 and 13 years with significant variation between individuals. However, the initial growth of breast tissue occurs during fetal development regardless of sex. Usually, females experience menarche about two years after thelarche has begun, with complete breast development from thelarche to adult breasts, taking between 2 and 4 years. Moreover, puberty is considered delayed if breast development does not start before age 13 or if a female has not had her first period (menarche) within three years of thelarche. Additionally, secondary breast development occurring before the age of 7 or 8 years could be a sign of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menstruation
Menstruation (also known as a period, among other colloquial terms) is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. The menstrual cycle is characterized by the rise and fall of hormones. Menstruation is triggered by falling progesterone levels and is a sign that pregnancy has not occurred. The first period, a point in time known as menarche, usually begins between the ages of 12 and 15. Menstruation starting as young as 8 years would still be considered normal. The average age of the first period is generally later in the developing world, and earlier in the developed world. The typical length of time between the first day of one period and the first day of the next is 21 to 45 days in young women. In adults, the range is between 21 and 31 days with the average being 28 days. Bleeding usually lasts around 2 to 7 days. Periods stop during pregnancy and typically do not resume during the initial months of breastfeed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fecal Incontinence
Fecal incontinence (FI), or in some forms encopresis, is a lack of control over defecation, leading to involuntary loss of bowel contents, both liquid stool elements and mucus, or solid feces. When this loss includes flatus (gas), it is referred to as anal incontinence. FI is a sign or a symptom, not a diagnosis. Incontinence can result from different causes and might occur with either constipation or diarrhea. Continence is maintained by several interrelated factors, including the anal sampling mechanism, and incontinence usually results from deficiency of multiple mechanisms. The most common causes are thought to be immediate or delayed damage from childbirth, complications from prior anorectal surgery (especially involving the anal sphincters or hemorrhoidal vascular cushions), altered bowel habits (e.g., caused by irritable bowel syndrome, Crohn's disease, ulcerative colitis, food intolerance, or constipation with overflow incontinence), and receptive anal sex.

Precocious Puberty
In medicine, precocious puberty is puberty occurring at an unusually early age. In most cases, the process is normal in every aspect except the unusually early age and simply represents a variation of normal development. In a minority of children with precocious puberty, the early development is triggered by a disease such as a tumor or injury of the brain. Even when there is no disease, unusually early puberty can have adverse effects on social behavior and psychological development, can reduce adult height potential, and may shift some lifelong health risks. Central precocious puberty can be treated by suppressing the pituitary hormones that induce sex steroid production. The opposite condition is delayed puberty. The term is used with several slightly different meanings that are usually apparent from the context. In its broadest sense, and often simplified as early puberty, "precocious puberty" sometimes refers to any physical sex hormone effect, due to any cause, occurring ...
